Yes, original owner, bought new in 2018. I also have a request in to Jayco too.
It is odd, the large slide does not have any Darco, etc. in place as you would expect on the bottom. The outside of the floor is coated in some green material. Appears to be sprayed on, as it is mildly textured and evenly distributed across the surface. Apparently pretty weak too, since it is coming off, even though the roller is working properly.
I will take a picture tomorrow if I have time.
